Title: Optical subscriber system fault recovering system
Inventor: SUZUKI SHUJI
IPC: H04B10/07
Filed: 1992-08-26
Abstract: PURPOSE:To recover the fault of an optical subscriber system without using any optical switch by switching either optical transmission after modulating a sub carrier with a signal or direct optical transmission while using a variable optical transmitter and variable optical receiver. CONSTITUTION:Normally, variable optical transmitters 10 in subscribers 102-104 convert inputted burst signals to optical signals as they are and output them, and a variable optical receiver 11 in a station 101 is also operated in the state of receiving the normal burst signals. In this case, assuming that any fault is generated at the subscriber 104 and the wrong optical burst signal is sent out, for example, the variable optical transmitters 10 of the subscribers 102 and 103 are changed so as to send optical signals for which the sub carrier is modulated by the burst signal, and the variable optical receiver 11 in the station 101 also changes the operation so as to demodulate the optical signals for which the sub carrier is modulated. Thus, signals can be transmitted from the subscribers 102 and 103 to the station 101 by using the optical signal, for which the sub carrier is modulated, without being disturbed by the wrong optical burst signal outputted from the subscriber 104.

Abstract: PURPOSE:To prevent the deformation due to the abnormal elongation of a shadow mask by changing a pressing force of the side edge-part of a mask blank- material, of the longitudinal direction of slot, from that of the direction perpendicular to said direction, in forming the curved surface of a slot type shadow mask. CONSTITUTION:In forming the curved surface of a shadow mask 1, the gas supplying holes of pressure-source cylinders 4 for applying a pressure to a blank holder 2 are communicated to an independent gas passage 5b capable of controlling only the longitudinal directions Y of slots S, as shown in the cross-sectional drawing of a press die at a B-B line. On the other hand, the other blank holder piece 9 for holding the side edge of the X-direction perpendicular to the Y-direction of mask 1 is incorporated in the holder 2, as shown in the cross-sectional drawing of press die at an A-A line. A gas passage 5c capable of controlling the X-direction separately from the gas supplying holes of cylinders 4 is formed in a manifold plate 5. In this way, the abnormal elongation in the X- direction of mask 1 can be adjusted by separately and optionally changing the pressure, for holding the edges of holder 2 in the X, Y directions of the mask 1 to be formed, respectively.

Abstract: PURPOSE:To obtain stable glow discharge with less preliminary discharge, by converging UV light, which is generated by preliminary discharge, at a desired position in a main discharge region by pivotable mirror surfaces, and yielding ionization at the position so that most of the UV light contributes to the ionization in the main discharge region. CONSTITUTION:The main discharge of an excimer laser apparatus occurs between main discharge electrodes 1 and 2 and a glow region 3 is yielded. Meanwhile, preliminary ionization generates UV light 6 between preliminary electrodes 4 and 5. The UV light 6 is converged by a reflecting mirror 9 which is provided behind, and a focal point is formed at a point 11. The reflecting mirror is an elliptic mirror. The first focal point is set at a part, where the UV light 6 is generated, and the second focal point is set at the point 11. Then the UV light 6 is efficiently converged in the main discharge region even if the UV light has less discharge power. Thus sufficient amount of ionized electrons can be obtained. When the mirror can be turned around a supporting post 10, the focal point 11 can be adjusted so that the point 11 is located at the desired position between the main electrodes 1 and 2. The main discharge can be performed along the entire length between the main discharge electrodes 1 and 2.

Title: Lightning arrester element
Inventor: KANI AKIRA
IPC: H01T4/12
Filed: 1993-09-16
Abstract: PURPOSE:To shorten the delay time in discharging and lessen the dispersion in the operation voltage by forming an aux. electrode at the outside surface of an insulated vessel, lessening the electrode distance forming a capacitor. and enlarging the electrode area. CONSTITUTION:An aux. electrode 6 is formed at the outside surface of a cylindrical vessel 1 of a lightning arrester concerned. This aux. electrode 6 is embodied in a line form parallel with the direction of discharging and connected with one of the metal lids 3 where a discharge electrode 5 is formed in a single piece structure. The aux. electrode 6 can, for example, be made simply by printing an Ag conductor ink followed by baking. Such a configuration is also acceptable that another aux. electrode 6' in a ring form is provided-in such an arrangement as surrounding the circumferential surface of the insulative vessel 1 independently without being connected with aux. electrode 5. Because the electrode distance forming a capacitor is lessened in this aux. electrode and the electrode area is enlarged, it is practicable to make the accumulated electric charges very large. This permits shortening of the delay time in discharging to lead to lessening of dispersion in the operation voltage.

Title: Code error detection circuit
Inventor: ARAI MASANORI
IPC: H03M13/00
Filed: 1984-11-29
Abstract: PURPOSE:To detect a code error with a simple circuit by generating a pulse from a storage means when an input signal has an error in the code rules in the synchronization establishing state. CONSTITUTION:A signal (a) comprising an mB1C code is inputted to an EX-OR circuit 2 together with a signal (b) while being delayed by 2 bits at a delay circuit 1, the dissidence of them is detected to generate a signal (c). This is a signal outputting '1' at each (m+1)-th bit when no code error exists. A frequency divider 3 applies 1/(m+1) frequency division to a clock (d) having a bit period to produce a signal (e). A flip=flop 4 receives the signal (c) at the data input D and the signal (e) at the clock input C and produces an output signal (f) of '1' level continuously when the synchronization is established and no code error exists. If any code error exists, however, one pulse of '0' level is generated and it is used as an error signal to detect the error.
